  Photoinduced Free Radical Chemistry of the Acyl Tellurides: Generation, Inter- and Intramolecular Trapping, and ESR Spectroscopic Identification of Acyl Radicals

  摘要：

  Acyl tellurides are prepared in good to excellent yield by the reaction of sodium aryl tellurides with acyl chlorides, or mixed anhydrides, and are found to be moderately air-stable substances. In contrast to previous literature reports, acyl tellurides of aryl and vinyl carboxylic acids are found to be excellent sources of acyl radicals on photolysis with a simple white light source. The acyl radicals so generated may be trapped intermolecularly by dichalcogenides, or by TEMPO in excellent yield. Trapping by N-tert-butyl-alpha-phenyl nitrone produces a stable nitroxide radical which has been characterized by ESR spectroscopy. The very efficient trapping of acyl radicals by acyl tellurides themselves is demonstrated by a crossover experiment. Acyl tellurides are shown to participate in very efficient radical cyclization reactions onto alkenes with the formation of five-, six-, and eight-membered rings. The immediate products of the cyclizations onto alkenes are alpha-[(aryltelluro)methyl] ketones and the chemistry of these relatively unstable species is briefly described. Treatment with hydrogen peroxide affords alpha-methylene ketones in high yield. When elimination of the aryl telluro group is not possible the alpha-[(aryltelluro)methyl] ketones are stable species that may subsequently be employed in further radical chain reactions, for example with tributyltin hydride and methyl acrylate. Cyclization onto alkynes yields alpha-[(aryltelluro)methylene] ketones which are stable species and which take part in substitution reactions with higher order cuprates or with diphenyl diselenide.

  An efficient synthesis of carbo- and heterocycles using CC, CO and CN bonds under cobalt catalysis is described. The substituents on olefins are key for controlling the regio- and chemoselectivity in the initial hydrogen atom transfer step and quaternary carbons are efficiently constructed under mild conditions. Cyclopropane cleavage and tandem cyclization give highly functionalized bicyclic skeletons

• Formation of dibenzofurans by flash vacuum pyrolysis of aryl 2-(allyloxy)benzoates and related reactions

  Flash vacuum pyrolysis (FVP) of aryl 2-(allyloxy)benzoates 5 and of the corresponding aryl 2-(allylthio)benzoates 6 at 650 °C, gives dibenzofurans 19 and dibenzothiophenes 20, respectively. The mechanism involves generation of phenoxyl (or thiophenoxyl) radicals by homolysis of the O-allyl (or S-allyl) bond, followed by ipso attack at the ester group, loss of CO2 and cyclisation of the resulting aryl

  在650℃下，对 2-（烯丙氧基）苯甲酸芳基酯5和相应的2-（烯丙硫基）苯甲酸芳基酯6进行快速真空热解（FVP），分别得到二苯并呋喃19和二苯并噻吩20。该机制涉及产生苯氧基 （或者 噻吩氧基）通过O-烯丙基（或小号烯丙基）键，然后在酯基上进行ipso攻击，CO 2损失和所得芳基自由基环化。综合而言，该方法对p-取代的底物效果很好，可产生2-取代的二苯并呋喃19b-f（73-90％）和二苯并噻吩20b-c（90-94％）。在m-取代的底物的环化以及自由基与取代基和ipso-攻击的竞争性相互作用中，几乎没有选择性显示出o取代的底物的热解复杂化。相关自由基前体的FVP包括2-（烯丙氧基）苯基苯甲酸酯43没有产生二苯并呋喃，而2-（烯丙氧基-5-甲基）偶氮苯 44降低了产量。通过FVP不能获得咔唑2-（烯丙基氨基）苯甲酸4-甲基苯酯 42。

  convert to cyclic conjugated enones in moderate to good yields. In addition, the reduction−oxidation reaction sequences can be successfully performed in one pot. The regioselectivities of cyclopropane ring opening in the bicyclic substrates depend on the oxidizing agents used. For example, reactions promoted by FeCl3 with pyridine lead to the expected ring-expansion process involving internal-bond cleavage

  io二碘化物促进了各种α-溴甲基环烷酮的反应，然后用三甲基甲硅烷基氯进行处理，导致嵌在双环[ m .1.0]烷烃骨架中的环丙基甲硅烷基醚的生产。用氧化性电子转移试剂（例如Fe（III），Ce（IV）和Mn（III）盐）处理醚时，会生成扩环酮，并以中等至良好的产率转化为环状共轭烯酮。另外，还原氧化反应序列可以在一锅中成功进行。双环底物中环丙烷开环的区域选择性取决于所用的氧化剂。例如，FeCl 3促进的反应用吡啶导致预期的扩环过程，该过程涉及双环烷烃的内部键裂解并产生环烯酮作为最终产物。相反，与Ce（NH 4）2（NO 3）6或Mn（OAc）3作为氧化剂的反应通过外键裂解进行，得到α-碘甲基环烷酮。
